In 2005 when the Scottish grid was aligned with England / Wales energy trading arrangements the Scottish power stations had to demonstrate grid compliance, including improved load control and grid frequency regulation control.

Scottish Power contracted Capula Ltd to design new BETTA-Compliant control systems for their Cockenzie (4x300MW) and Longannet (4x600MW) coal fired power plants. As lead engineer Craig Powers was responsible for project concept, overall design, implementation team lead, test, commissioning, delivery and quality of the Turbine Load and Boiler firing control for the 8 generating boilers. The Cockenzie project also involved the replacement of most of the boiler auto controls in a very short project time frame. This was a very challenging project with two distinct customers, two diverse power plants (one hard desk, one soft desk), 8 generating units/boilers, all to be delivered from concept to go-live in 9 months. Both plants used iFix and Siemens Moore APACS.
